OIL-CAriE TRIMMER.

SPECIFICATION forming part of Letters Patent No. 584,401, dated June 15,1897. Application filed April 9, 1897. Serial No. 631,398. (No model.)

To all whom it may concern:

Be it known that I, JOHN B. RAAB, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Oil-Oake Shavers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention relates to a machine for shaving the edges of oil-cakeafter said cake comes from the press.

As preliminary to the specification and as an aid to a correctunderstanding and appreciation of my invention I will briefly outlinethe method heretofore common in performing the work that this inventionis designed to perform in a vastly more satisfactory manner. Theoil-press, which is a wellknown means for extracting the oil fromlinseed, cotton-seed, and other oil-containing products, in itsoperation of extracting the oil compresses the seed into a cake, the oilbeing removed therefrom by the pressure. In this operation ofcompression more or less of the oil is forced into the outer edges ofthe cake, where it remains. It is desirable to reclaim this oil to beagain passed through the press with other seed or substance. Thisoperation of removing the edges of the cake is done by manual labor andrequires the cake to be taken hold of by the hands and moved against theedge of a stationary planer as many times as there are edges to thecake, and it frequently becomes necessary to pass the same edge of thecake over the planer two or more times. This hand operation is slow andtedious and has other disadvantages. Owing to the exceedingly-heatedcondition of the cake when it comes from the press, it is very severe onthe hands of the operator, and it is difficult to retain labor for thiswork for any length of time. The object, therefore,

of this invention is to provide amachine for such work which has acapacity for doing the work much quicker and dispenses with thenecessity of handling the cake manually.

To these ends the invention consists of parts, their construction andarrangement, all as will appear from the following description, taken inconnection with the accompanying drawings, of which Figure 1 is a sideelevation of my machine. Fig. 2 is a top plan view. Fig. 3 is alongitudinal mid-sectional View. Fig. 4 is a front elevation. Fig. 5 isa detached side elevation of the plunger.

Throughout the specification similar letters of reference indicatecorresponding parts.

The base or lower frame A of the machine is preferably constructed oftimber. The upper frame 13, which provides the bearings, is preferablyconstructed of metal, substantially as shown in the drawings, or anyvariation therefrom that may be deemed desirable.

O designates an oblong rectangular box or casing, of metal, occupying atransverse position on the frame and having a longitudinal flaring mouth0. O is a longitudinal openingin the floor of said box, communicatingwith an opening D in the top of the lower frame or base portion. Thisopening D communicates with a flaring space D, inclosed by two slantingwalls D D. The 0il-containing edges of the cakes when they are removedfall through these openings into a convenient place to be carried fromthe machine forfurther treatment.

E designates an oblong rectangular frame constructed of metal with itsvertical sides entirely open and its horizontal and vertical edges 6 e e6 formed into knife-edges with rounded corners and projecting inwardlyon the machine. This frame is rigidly mounted in the casing Osubstantially in the position shown clearly in Fig. 3.

F designates a reciprocating plunger movable horizontally in the casingO and in and out of the frame E back and forth across the openings O andO. This plunger has rigidly connected to its rear side two horizontalarms F F, that project from bosses F rearwardly through guide-openingsin the rear vertical wall of the casing O and are flexibly connected totwo links F F, which are flexibly connected to eccentrics G G. Thelatter are rigidly mounted on the two short shafts G G, which arejournaled in the upright parts of the metallic frame.

The plunger E is properly guided in its reciprocating movement by twoupper angular arms H H, which project from the arms F F on the outerside of the case 0 and reach over the top of said case. The horizontalportions of these arms H II are inclosed between guides H H on the upperside of the case. When said arms are projected over the opening 0 on theouter movement of the plunger F, the said opening is closed against anyentrance of cake at an improper time. The lower guides for said plungerconsist of two downwardlyprojecting arms H II", that project from thebosses F F and rest upon rounded tracks 1 F in the bottom of the case 0.The lower ends of the arms H H are hollowed out to fit over the tracks FF The plungeris shown in full and broken lines in Fig. 3 to indicate thelimit of its inward and outward movements. These movements are obtainedby driving the shafts G G, which is done through the following gearing.I I designate two spur-wheels keyed to said shafts.

I I are two smaller spur-wheels on the main driving-shaft J below thewheels I I and meshing therewith. The main shaft J is driven from aline-shaft by a belt which incloses a main drive-pulley J.

WVhcn the plunger is in its inmost position, as shown in broken lines inFig. 3, the cake is fed into the opening 0 to a position in front ofsaid plunger, where it rests upon the tracks F F The outward movement ofthe plunger pushes the cake forward into the frame E. The cake beingsomewhat larger than the frame the edges of said cake, which contain aquantity of oil, are cut off by coming in contact with the knife-edges ee. The edges thus cut off fall downwardly through the lower opening C.is forced into the frame E by the plunger dislodges the cake that waspreviously forced therein, and the said dislodged cake is received by anincline K,down which it descends to a series of reducing-rollers. Thesereducin g-rollers consist of three toothed rollers ff f and two smoothrollers g g. The toothed rollers grind the cake or reduce it to a stateof granulation, after which the smooth rollers operate to further reduceit to a fine state for various uses.

The roller f is-driven from the main drivingshaft J by means of a belt0, and from said roller f the remaining rollers are actuated by a trainof gears. The casing O is rigidly mounted between two side plates 0 Gwhich are bolted thereto and to the frame.

Having described my invention, I claim- 1. In a machine for shaving theedges of oil-cake, the combination with a frame, of a The nextsucceeding cake that,

case mounted thereon and provided with longitudinal openings in itsupper and lower sides, a frame provided with a knife-edge rigidlymounted in said case, and a reciprocating plunger in said case movablein and out of said frame, and adapted to force oilcake into said frame,whereby the edges of the cake are severed, substantially as described.

2. In a machine for shaving the edges of oil-cake, the combination witha supportingframe, of an oblong rectangular case mounted across saidframe, the said case being provided with a longitudinal opening in itsupper side through which the oil-cake is fed, and a similar opening inits bottom through which the severed edges of the oil-cake pass from themachine, a rectangular open frame rigidly mounted in said case, theinner orinclosed edge of said frame being of a knifeedge form, areciprocating plunger movable in said case in line with said knife -edgeframe, and means for supporting the oil-cake in a proper position infront of the plunger, substantially as described.

In a machine for shaving the edges of oil-cake, the combination with asupportingframe, of a rectangular case mounted on said frame, the saidcase having longitudinal openings in its upper and lower sides, aknifeedge frame mounted in the front portion of said case, areciprocating plunger movable in said frame and adapted to sever theedges of the oil-cake as the said cake is forced into the frame, andguides to direct an even movement of said plunger, substantially asdescribed.

el. In a machine for shaving the edges of oil-cake, the combination witha supportingframe, of a reciprocating plunger, a case in which saidplunger moves, and in which the oil-cake is supported in front of theplunger, a knife-edge frame mounted in said casein the front of theplunger, eccentrics, flexible connections between said eccentrics andthe plunger, and means for driving said eccentrics, substantially asdescribed.

5. In aunachine for shaving theedges from oil-cake, the combination witha frame, of a case mounted across said frame with openings therein,tracks lying across the lowerone of said openings, at knife-edge framemounted in said case, a reciprocating plunger adapted to force theoil-cake through said knife-edge frame, and to thereby sever the edgesof the cake, and a series of reducing-rollers adapted to receive thecake from the knife-edge frame, substantially as described. I

In testimony whereof I affix my signature in presence of two witnesses.
